A good example: there was recently a thread on the Julia discourse comparing Julia and Mojo. Julia used no external libraries (compared to 7 with Mojo) implemented a simpler, faster, and cleaner version of the Mojo code that was used to showcase how fast Mojo was: https://discourse.julialang.org/t/julia-mojo-mandelbrot-benc.... Then further still, folks were able to optimize for even more speed with various abstractions that let Julia take more advantage of the hardware.

That's the promise I think Julia makes and delivers on - you can write incredibly "fast" code simply and cleanly. Yes, you can have a higher standard of "fast" which requires a bit more advanced knowledge but I'd argue that Julia still offers the cleanest/simplest way to take advantage of those micro-optimizaitons.
